The man shot and killed in a house in the 2100 block of South Wirt Avenue was identified Saturday as Anthony McGrone, 28, of Springfield.

McGrone and a second man were shot about 4:30 p.m. Friday. Police said the second man, a 36-year-old whose name has not been released, sustained a gunshot wound to the head. He was treated and released at Memorial Medical Center.

McGrone was pronounced dead at 4:56 p.m. at Memorial's trauma center. The gunshot wound is consistent with a homicide, a press release from the Sangamon County coroner's office said.

Witnesses said they saw two males running from the area in an eastbound direction. Police brought in a dog to track the two people, but the dog was unsuccessful.

As of Saturday, the case remained under investigation. No arrests had been made.

Detectives continued to follow up on leads and were conducting interviews, a press release from the city said.

State Journal-Register newspaper archives indicate McGrone was one of three people arrested in January of 2013 when police served two search warrants in Springfield and seized more than six pounds of marijuana. He was later convicted of possession of marijuana.

McGrone was also convicted of possession of marijuana in 2006, information from the Sangamon County Clerk of Courts office indicates.

On Saturday morning, less than 24 hours after the shooting, members of CeaseFire were knocking on doors in the neighborhood where the shooting occurred and talking to residents.

CeaseFire is an anti-violence program that recently started operations in Springfield. Larry Hemingway Sr., a Springfield Urban League employee and CeaseFire's manager, said they wanted to tell people about their program, and also support family and friends of the shooting victims.
